Method and apparatus for selecting a beam combination in a MIMO wireless communication system
Abstract
A method and apparatus for selecting a beam combination of beam switched antennas in a multiple-input multiple-output (MIMO) wireless communication system including a first node and a second node. The first node sends a plurality of modulation and coding scheme (MCS) requests to the second node. Each of the plurality of MCS requests is sent using a particular beam combination. The second node receives the MCS requests and generates MCS feedback signals for each of the MCS requests. Each MCS feedback signal includes an MCS recommendation for the particular beam. The first node selects a beam combination for communicating with the second node based on the MCS recommendations.
